On some systems missing gnu/stubs-*.h files make -m32/-mx32 compilation
checks fail. As we want to support multiple personalities despite of
this limitation, workaround the check by creating empty gnu stub files
if necessary.
* m4/mpers.m4 (st_MPERS): Check for the gnu stub file. Create an empty
gnu stub file if the system one is missing.
* Makefile.am (DISTCLEANFILES): Add gnu/stubs-32.h and gnu/stubs-x32.h.
Fix multiple personalities support in parsers of utimes, futimesat,
and utimensat syscalls by introducing two mpersified printers:
print_timeval_pair and print_timespec_utime_pair.
* print_time.c: New file.
* Makefile.am (strace_SOURCES): Add it.
* utimes.c (decode_utimes): Remove.
(sys_utimes, sys_futimesat): Use print_timeval_pair instead
of decode_utimes.
(sys_utimensat): Use print_timespec_utime_pair instead of decode_utimes.
Add a subsystem for semi-automatical definition of how parsers should
work with personality-dependent (mpers) types of tracee's data. Create
auxiliary libraries containing mpers syscall parsers and printer
functions, one library for each possible nonnative target personality.
Currently some parsers do not handle differences in definitions of data
types between personalities, namely LP64 and ILP32. When
this is the case, long integers, pointers, and all compound
types containing long and pointer members may be printed incorrectly,
because of differences in sizes, offsets and alignments.
Since in most cases these are the only differences in desired behaviour
of parsers and printers for different personalities, a correct way
would be to compile one source code into multiple parsers, differing
only in definitions of mpers types.
To get a definition of a given type for nonnative personality
a very basic .c file containing a declaration of a variable of this type
is being compiled for this personality (using -m32 or -mx32 compiler
flag). Information about the type is then being extracted from
this binary's DWARF debug info with an awk script and put
into a corresponding header file. Resulting headers are being used to
compile mpers variations of syscall parsers and printer functions.
In addition to syscall parsers, there can occur a need to create mpers
printing functions, which then can be called from many places
in the code (for example, printsiginfo_at). Such functions (printers)
are marked in a special manner.
For each possible nonnative target personality a library is being
created, containing mpers variations of syscall parsers and printers.
Only syscall parsers from files marked in a special manner and specially
marked functions from such files are being recompiled and included
in these libraries.
generate_mpers_am.sh is called by bootstrap to find the files
from strace_SOURCES which include MPERS_DEFS. During compilation,
these files are being inspected for inclusions of DEF_MPERS_TYPE,
and nonnative variations of each included type are being generated
by an awk script.
Mpers parser names are being modified during inclusions of syscallent
headers for nonnative personalities. Pointers to printers are
being stored in structs struct_printers, and a master
pointer printers is being updated on every set_personality.

Personality 1 for sparc and sparc64 appears to be an old attempt
to support stracing Solaris binaries.
It stalled after the only syscall, solaris_open, was covered:
all other solaris_foo's are printargs.
This change deletes personality 1. Now sparc is an one-personality
arch, and sparc64 is a two-personality one.
For clarity, pure renaming of personality 2 files to personality 1 for sparc64
is performed in the next commit - this prevents a state where syscallent1.h
seems to indergo a lot of changes, where in fact in is deleted, and then
replaced by syscallent2.h
Therefore, tree at this commit will not build.

Historically, only 16 bits (8-bit number and 8-bit type) of 32-bit ioctl
commands were used for decoding, which was the source for numerous
annoying collisions like this:
ioctl(0, SNDCTL_TMR_TIMEBASE or SNDRV_TIMER_IOCTL_NEXT_DEVICE or TCGETS, {B38400 opost isig icanon echo ...}) = 0
ioctl(0, MGSL_IOCGPARAMS or MMTIMER_GETRES or MTIOCTOP or SNDCTL_MIDI_MPUMODE, 0x7fffd47f7338) = -1 ENOTTY (Inappropriate ioctl for device)
The solution is to use all 32 bits for decoding, not just "number" and
"type", but also "size" and "direction".
As some architectures override defaults that come from asm-generic/ and
provide alternative definitions for some ioctl commands, we support
per-architecture ioctl definitions and merge them with common
definitions at build time. During the merge, we used to keep both
generic and architecture-specific definitions, now architecture-specific
definitions have precedence over generic ones -- ioctlsort omits
definitions from asm-generic/ for those ioctl names that have different
definitions in asm/.
Additional bits of "direction" are architecture specific -- the number
of bits and their values differ between architectures. To reduce
architecture differences in the source code, we keep "direction" in
symbolic form and compile it in ioctlsort.
Additional bits of "size" are also architecture specific -- not only the
number of bits differ between architectures, but sizes of many types
depend on sizeof(long). To reduce architecture differences in the
source code, we keep 32-bit and 64-bit versions of common ioctl
definitions, and use the appropriate version for each architecture and
personality.
To implement this, the tools for generating ioctl definitions from
kernel headers have been rewritten, and the source format of ioctl
definitions has been extended. The final ioctlent*.h files that are
included by syscall.c are now generated from source ioctls_inc*.h and
ioctls_arch*.h files at build time with ioctlsort.

While most of ioctl-related kernel headers are now exported by kernel's
headers_install, some are still modules_install only. The kernel's
headers installed into /usr/include/ are usually headers_install'ed and
therefore don't contain some internal headers we need. The solution is
to look for modules_install'ed headers for the running kernel, and fall
back to old behavior if they aren't found.

linux/sparc/{errnoent1,ioctlent1,signalent1}.h used to point to svr4/ files -
replace their contents with copies of used (and now deleted) files.
Make linux/sparc64/{errnoent1,ioctlent1,signalent1}.h include these files
instead of svr4/* ones.
Makefile.am: remove references to deleted files.
configure.ac: Remove a few tests which make no sense on Linux.
Man page: remove non-Linux quirks information.

user-specified file paths.
* Makefile.am (strace_SOURCES): Add pathtrace.c.

This unifies all the ioctlent.h's in the linux subdir while still
allowing each arch to maintain its own minor list.
The basic method is:
- each arch has linux/<arch>/ioctlent.h.in which defines only the
arch-specific ioctls;
- linux/ioctlent.h.in which defines only the common ioctls;
- at build time, these two headers are combined and sorted to produce
the linux/ioctlent.h file.
This also requires a little tweaking of the include files since the
common ioctlent.h is a built file.
